Chebyshevs

Chebyshevs is the plural form of the surname Chebyshev, derived from the Russian Чебышёв. In English-language mathematical literature the name is most often associated with Pafnuty Lvovich Chebyshev (1821–1894), a Russian mathematician whose work spanned probability, number theory, and analysis. The term Chebyshevs may be used to refer to multiple people bearing the surname, though Pafnuty Chebyshev is the best-known bearer.

Several mathematical constructs bear the Chebyshev name, reflecting his influence on the field. These include Chebyshev polynomials (the first and second kinds), Chebyshev’s inequality (a fundamental result in probability theory), and the Chebyshev distance (also known as the maximum norm), which measures the greatest coordinate difference between two points. Chebyshev’s work also contributed to approximation theory and the development of Russian mathematical education.
